High Mobility Multipurpose Wheeled Vehicle (HMMWV) (M998 Truck)

The High Mobility Multi-purpose Wheeled Vehicle (HMMWV) is the replacement vehicle for the M151 series jeeps. The HMMWV's mission is to provide a light tactical vehicle for command and control, special purpose shelter carriers, and special purpose weapons platforms throughout all areas of the modern battlefield. It is supported using the current logistics and maintenance structure established for Army wheeled vehicles. The HMMWV is equipped with a high performance diesel engine, automatic transmission and four wheel drive that is air transportable and droppable from a variety of aircraft. The HMMWV can be equipped with a self-recovery winch capable of up to 6000 pound 1:1 ratio line pull capacity and can support payloads from 2,500 - 4,400 pounds depending on the model. The HMMWV is produced in several configurations to support weapons systems; command and control systems; field ambulances; and ammunition, troop and general cargo transport.

The HMMWV is the world standard in light military trucks. It is lightweight, high
performance, four wheel drive, air transportable & droppable, land mobility system.
The family includes utility/cargo, shelter carrier, armament carrier, ambulance, TOW
missile carrier and scout-reconnaissance configuration. Payload varies by body style
ranging from 1920 lbs on the 4 litter ambulance to 5300 lbs on limited availability
Expanded Capacity variant, but is generally in the 5/4T range. A basic armor package
is standard on the Armament and TOW missile carrier models. A more heavily
armored, or Up-Armor HMMWV, is now being produced in limited quantities,
primarily for the Scout Platoon application. Special supplemental armor versions
have been developed for USMC requirements; unique model numbers designate these
configurations.

The weapons platform can be traversed 360 degrees. This confirguration of the HMMWV is equipped with the self-recovery winch.

The Up-Armored HMMWV is designed to conduct reconnaissance and security operations as its primary
function. Up-Armored HMMWVs are organic to the scout platoons of the armored, infantry, and mechanized infantry battalions. Up-Armored HMMWV-mounted scouts enhance the capability of scout platoons to provide accurate and timely information about the enemy and the area of operations.

During reconnaissance operations, the scouts provide the commander with a mobile reconnaissance platform to perform detailed route, zone, and area reconnaissance; prevent surprise by enemy forces; and help retain the freedom to maneuver. The speed, mobility, and stealth of the Up-Armored HMMWV also allows the scout to extend the depth of his reconnaissance, providing increased security and additional time and maneuver space for the commander. Due to its small signature relative to the Cavalry Fighting Vehicle (M3), the Up-Armored HMMWV provides the stealth necessary to conduct detailed reconnaissance in areas where contact with the enemy is possible. This information is rapidly reported to higher headquarters through secure radio means or by physical delivery (particularly during periods of reduced electronic communications).

Security operations are also significantly enhanced by Up-Armored HMMWV-mounted scouts. In screen
missions, scouts operating independently, or in conjunction with other reconnaissance elements, will be used to establish observation posts to the front or flank of the maneuver force, patrol between observation posts, and cover gaps between forces. In rear areas, Up-Armored HMMWV-mounted scouts enhance security by patrolling primary lines of communication, providing threat early warning to rear area units, and reconnoitering potential threat landing and drop zones.
